## Questions & Answers

**Q: Won't merino wool feel itchy? And what does 17.5 micron mean?**
A: 17.5 micron superfine merino fibers are finer than human hair — too fine to feel itchy, even on sensitive skin. Standard wool (25+ microns) causes irritation; this doesn't. OEKO-TEX certified, tested against 100+ harmful substances.

**Q: How do I wash and dry it to keep it looking new ? Will it shrink or lose shape?**
A: Machine wash cold max 30°C, delicate cycle, inside out. Lay flat to dry — tumble drying permanently damages merino fibers. Store clean and dry; keep merino in sealed bags to prevent moths. Wear 3–5 days between washes — merino resists odor naturally

**Q: Which weight should I choose — 165, 250, or 320 g/m²?**
A: 165 g/m² — active pursuits, travel, spring/summer, 40–60°F. 250 g/m² — cold weather, most outdoor activities, 25–45°F. 320 g/m² — frost and low activity, 10–35°F, extreme conditions. Rule: the higher the activity level — the lighter the weight.

**Q: Where does the merino wool sourced from and is this product certified?**
A: Our products are made from Australian merino wool, RWS certified — independent farm audit confirming animal welfare and land management standards. Every component tested against 100+ harmful substances under OEKO-TEX Standard 100.

**Q: Does it fit true to size?**
A: Choose your regular size. For a snug layering fit under jackets or ski gear, size down one

### ⭐⭐⭐⭐⭐ Fit
*by A***R on March 4, 2024*

I’m a 5’4”, size 14, XL size woman and I prefer to wear 30” tunic length tops. I couldn’t find women’s, merino base layer tunics, in that length for any price! I decided to try a men’s Large and after reading the reviews that stated these shirts are long and reading a review that said the sleeves ran a little short, I ordered this shirt. It is beautiful! It’s butter soft, well made, not scratchy and most importantly it fits! The shoulders and arms are roomy, not baggy. The arm length is a little long on me, as expected, but not too long. The torso length is perfect!!!! It falls just below my hips! It’s kind of snug in the hips, but that’s to be expected in a man’s size and I’m a woman with big hips. I can live with that. I will be ordering a half zip on the same size ASAP! If you’re a medium to large size woman, who prefers tunic length base layers, but can’t find one in women’s sizes, buy this shirt. It’s worth every penny! Well done!!!! Update: I put the sweater through a rinse cycle and reshaped the bottom part it to make it drape around my hips. That worked perfectly! I read a review that stated they thought the sweater had some percentage of spandex. I disagree, because, I would have been unable to reshape the sweater so easily if it contained anything like that. I just wanted to mention that. Thanks for an absolutely amazing piece of clothing!
